What are two things that an access point （AP） does when it receives an 802.11 frame from a Wi-Fi Multimedia （WMM） client？ （）A、EAP-FASTEAP-FAS Access Point Protocol （LWAPP） packet is used to generate an 802.1 p priority value in the packets， which are sent to an Ethernet switch by the controllers.B、The AP will police the 802.1 le priority value to ensure it does not exceed the maximum value allowed for the QoS policy that is assigned to that client.C、Once the LWAPP packet is received， the AP generates the IEEE 802.1 p priority value.D、The AP will map the 802.11e priority value to the DSCP value.E、The AP will map the DSCP value to the outer LWAPP frame.
